Use this calculation when every balance, flow, and elapsed period follows the same accounting basis, currency, entity boundary, and reporting period. It is useful for a reproducible schedule or analytical cross-check, but the result should still reconcile to the ledger.

Average accounts receivable

Average accounts receivable balance for the period, for example beginning plus ending divided by two.

Credit sales

Total credit sales for the same period; cash sales are excluded from days sales outstanding.

Days in period

Number of days in the measurement period, such as 30, 90, or 365.

The implemented rule is: Calculate days sales outstanding as average accounts receivable divided by credit sales, times the number of days in the period.^[1]

Days sales outstanding

Average collection period in days; higher values mean slower collections.

The calculator applies the stated arithmetic and does not decide whether a recognition method or classification is permitted under a particular accounting framework. Estimates, cutoff errors, seasonality, acquisition effects, inconsistent averages, and differing policies can make a mathematically correct result misleading.

Reconcile the inputs to the general ledger and supporting schedules. For reporting decisions, compare the result with the entity's accounting policy, applicable GAAP or IFRS guidance, prior-period disclosures, and an accountant's review.

• Cash Conversion Cycle Calculator

  Calculate the cash conversion cycle in days as days inventory outstanding plus days sales outstanding minus days payable outstanding.

• Payable Turnover and Days Calculator

  Calculate payable turnover and payment days from credit purchases and average accounts payable for the same period and currency.

• Operating Cycle Calculator

  Calculate the operating cycle in days as days sales in inventory plus days sales outstanding, the time from acquiring inventory to collecting cash from sales.
